3. Problem Statement An expansion joint (EJ) connects pipes together in large systems to allow for the settling of a system. Garlock makes many styles of EJs to fit different size pipes and to hold up against different environmental factors. The current version is used in systems without any detection of imminent failure besides visual inspection. Many EJ’s are in hard to reach places and data acquisition is needed to monitor their status. The goal of this project is to create a sensor package that can monitor the integrity of an EJ it is installed in and recognize possible failure situations. An EJ with the installed sensor package should be able to withstand a prescribed amount of thermal, pressure, and mechanical cycles. The installed sensor package should be implemented with no significant loss to the integrity of the EJ.

4. Expansion Joints Bolted between pipes Made of Rubber, Fabric and Metals Diameters of 2’’ to 130’’ Subjected to: Multiple working fluids, Pressures, Temperatures Contraction, Expansion Torsion, Vibration

5. Prior Project – P13671 Test Rig for Garlock Expansion Joints Has ability to test/measure both temperature and displacement cycles Garlock has ability to also test pressure at their facilities

6. Benchmarking No system in the market Difficult to measure composite/rubber degradation Multiple reasons for degradation Current method is regular preventative maintenance Visual Inspection Qualitative data no quantitative data

7. Our Goal Deliverables Sensor package for EJ’s 4in and larger Be able to predict impending EJ failure Stretch Goals: Wireless Transmission of Data (based of previous MSD project) Mountable on any type of EJ

8. Customer Requirements Monitor losses in integrity Withstand working environment Easy data access Applicable to many sizes and types Compatible with existing hardware Alterations must not significantly affect the strength of the EJ Mountable on an EJ
